upgrade

It seems you learn (or don't learn from past mistakes) every day. I was trying to do an upgrade tonight and just finished wrangling with the server for over an hour. It seems that Drupal 6.x really doesn't like it if you rename your theme directory and then create a new theme directory with the old name with your new files.

It caused all kinds of problems and eventually the web server starting throwing 503 service unavailable errors which will really make you scratch your head. I thought I was being smart by keeping a handy backup of the old theme directory in case something went wrong. Instead, it ended up just causing me a ton of headaches.

Once I realized the web server was fine and it was actually Drupal that was messed up, I simply started from scratch with my old Drupal installation. Then I deleted the theme folder and replaced it with the updated theme. Then I did a submit on the themes page (Site Building > Themes) and everything was fixed.
